Appendix
The maximum steady-state output power is limited to a total of 850 W
for any combination of output voltages/currents at low-line 100-120 VAC
nominal input voltage conditions.
The maximum steady-state output power is limited to a total of 625 W
for any combination of output voltages/currents, excluding the 50 VDC
source at low-line 100-120VAC nominal input voltage conditions. This
limitation is required to ensure that there is sufficient PoE power or 225
W total at this input voltage condition.
The maximum steady-state output power is limited to a total of 950 W
for any combination of output voltages/currents, excluding the 50 VDC
source at high-line 200-240VAC nominal input voltage conditions. This
limitation is required to ensure maximum PoE power or 450 W total for
the 50 VDC source at this input voltage condition.
To obtain the full output rating of 1400 W, you must connect the power
supply to a nominal (200-240 VAC) input power voltage source.
